New hainan clients, the south china sea net, the south china metropolitan news, 4 january (journalist rich), "sprung" cabbage, cabbage greens from the small holes of the drifting floats, and fat-tailed fish swimming under the drifting board... ... On january 4th, new hainan client reporter passed the chinese vegetable base in sanya cityVegetablesA new technology was seen in the facility sheds to live in two industries, raising fish without changing water, growing vegetables without soil and fertilization. This is the new model of high-efficiency agriculture in sanya cityFish and vegetablesI don't know。

We don't need soil to grow our vegetables
“at present, 16 acres of hydroponic vegetables are being harvested, producing more than 1,500 kg per acre.” the technical staff of the institute of tropical agricultural sciences of sanya city, chen moo, picked a few oily cabbages from the float board and said that hydroponic vegetables had the advantages of short-lived growth cycles, small pests, year-round planting and weather-free food, compared to normal soil cultivation, so that growing vegetables was no longer dependent on the sky。
In order to guarantee a stable market for vegetables over the years and to increase the efficiency of base vegetable production, the sanya rural agricultural department has been actively exploring new patterns of perennial vegetable cultivation, breaking down traditional ground farming patterns, boldly applying hydroponic techniques, building sheds for hydrovegetation facilities and promoting the planting of 16 acres of hydrovegetable vegetables at the sanya ridge gate perennial vegetable base。
Chen moo-hong said that so-called hydroponic vegetables were grown up by root to absorb the nutrients of the formula, without the need for soil and fertilizers. Hydraulic systems do not destroy the original structure of the soil and prevent contamination of the soil with heavy metals and other pollutants. The production environment is conducive to ensuring the safety of vegetable production and is a green and green form of cultivation。
It is understood that hydroponic vegetables are grown entirely on the basis of “drinking water” and, generally speaking, a hydroponic vegetable from seed to harvest takes about 20 days in summer and 25 days in winter. “the seeds are planted in the ploughs, then planted in the pores of the floats in the ponds, and the nutrient cycling system is activated so that the vegetables can grow.” chen shih said the same vegetable would take about 45 days to grow in the soil。

The fish don't change the water
How can the development of circular agriculture make it more economically valuable? How to widen the revenue channel? A study conducted by the department of agriculture and rural development of sanya city and the institute of tropical agricultural sciences of sanya city led to the identification of patterns of recycling and efficient farming for fish and vegetables。
Following the lifting of the pavilion full of green green green vegetables in the water-breeding vegetable pool, the gillfish that was roaming under the ground was moving around. “the symbiotic principle is that fish dung is absorbed in a hydroponic pool through bioresolved nutrients to feed vegetables, forming a closed ring pattern.” ran zihan, head of co-prosperative technology at the institute of tropical agricultural sciences of sanya city, described co-production as a relatively new and complex farming model, which developed two different farming techniques, aquaculture and water farming, which, through sophisticated eco-designs, continued to feed fish-generated nitrogen and faeces, through the water cycle to the root of the vegetables, thereby ensuring the water fattening of the vegetables. At the same time, “nutrient fluids” absorbed by vegetables after “fertilization” are available for fish to grow, culminating in “fish without water, soil and fat” and, ultimately, fish and vegetables。

Broaden access to industryQuality agricultural development
Combining fish farming and vegetable growing with complementary approaches to the recycle of facilities in agriculture is a model that can be promoted as a priority in future agriculture. “the new model of symbiotic fish and vegetables, while expanding industrial channels and achieving agricultural intensification and efficiency, can contribute to high-quality agricultural development in sanya and rural revitalization.” the director of the agricultural and rural directorate of sanya said:。

It is understood that agricultural production is becoming more efficient as science and technology develop. The combination of fish and vegetables, which solves the problem of water purification in fisheries, the recycling of water and the production of high-quality water products and vegetables in a hot shed, and the co-generation of fish and vegetablesGreen ecologyCyclical combinations produce more green, safe and ecologically good agricultural products。
